wideband enable

Function

The wideband enable command enables the wideband function, that is, the 4.9 GHz frequency band, of the regulatory domain profile.

The undo wideband enable command disables the wideband function, that is, the 4.9 GHz frequency band, of the regulatory domain profile.

By default, the wideband function of the regulatory domain profile is disabled.

Only the AP8130DN-W and AP8150DN support the 4.9 GHz frequency band.

Before using the 4.9 GHz frequency band, ensure that you have obtained the 4.9 GHz license from the local administrative department and use the band properly.

Usage Guidelines

The wideband function enables AP radios on the 5 GHz frequency band to use the 4.9 GHz frequency band. The 4.9 GHz frequency band is applicable to outdoor backhaul scenarios but not wireless coverage services. It is mainly used by WDS and Mesh backhaul links. The 4.9 GHz frequency band is out of the channel range reselected using DFS.

The following table lists channels and frequency distribution of the 4.9 GHz frequency band.

Channel No.	Parameters	Description
184	Frequency Band	4.9G
	Center Frequency (MHz)	4920
	Upper Frequency (MHz)	4910
	Lower Frequency (MHz)	4930
188	Frequency Band	4.9G
	Center Frequency (MHz)	4940
	Upper Frequency (MHz)	4930
	Lower Frequency (MHz)	4950
192	Frequency Band	4.9G
	Center Frequency (MHz)	4960
	Upper Frequency (MHz)	4950
	Lower Frequency (MHz)	4970
196	Frequency Band	4.9G
	Center Frequency (MHz)	4980
	Upper Frequency (MHz)	4970
	Lower Frequency (MHz)	4990

The 4.9 GHz frequency band supports channel bandwidths of 20 MHz and 40 MHz. Channels 184+188 or 192+196 can be bundled into a 40 MHz channel. Similar to the 5 GHz frequency band, the 4.9 GHz frequency band complies with 802.11a/n/ac.

After the wideband function of the regulatory domain profile is enabled, APs bound to this profile are automatically reset.

Example

# Enable the wideband function of the regulatory domain profile.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] regulatory-domain-profile name huawei
[HUAWEI-wlan-regulate-domain-huawei] wideband enable
Warning: To use the 4.9 GHz frequency band, apply for a license from the related department. When this frequency band takes effect, 
the AP will be reset. Continue? [Y/N]y
